This study shows that immersive VR can efficiently measure color discrimination with high throughput and reliable results, replicating known color discrimination asymmetries.

Red-green color-deficient observers sorting 450 Munsell chips into eleven basic categories retained structured categories; agreement, retest reliability and prototype stability fell stepwise from trichromats through anomalous trichromats to dichromats.

The paper presents a three-dimensional empirical metric field for color discrimination in sRGB space, showing spatially smooth and consistent structures across observers.

The paper shows human color discrimination asymmetry arises from ecological color statistics, supported by psychophysics, MEG, and deep neural networks.

This paper shows that tiny neural networks can accurately replicate human gloss perception judgments better than larger networks estimating physical reflectance.

This study investigates how surrounding colours affect colour constancy in virtual reality by manipulating lighting and object properties.

This study examines how humans adapt eye, hand, and head movements during a continuous visuomotor task, showing strategic adjustments improve performance.

This study measures contrast sensitivity in the far periphery for achromatic and chromatic stimuli, revealing underestimation by current models and differences in sensitivity decay patterns.

The paper investigates metacognitive sensitivity for the accuracy of eye movements by having participants judge their tracking performance of a moving dot cloud.

The paper investigates task-specific oculomotor routines for perceptual judgments of object width and height in virtual reality, finding distinct gaze patterns and performance consistency across free and constrained gaze conditions.

This study investigates factors influencing predictive eye movements in naturalistic scenes, finding that expertise, available information, and intact kinematic cues are critical for accurate predictions.

This study measures how well participants can judge color and gloss of objects under different lighting conditions, finding high accuracy in hue but poor performance in chroma, lightness, and gloss.

This study investigates how the single color appearance of iridescent objects varies with shape complexity, viewing angle, and motion, finding that hue similarity in multi-color matches best predicts single color appearance.

The paper investigates how the brain achieves color constancy by measuring neural responses to colored and neutral patches under different illuminations and finding that apparent color is represented in early visual cortex.

The paper shows individual differences in visual salience along semantic dimensions, with stable patterns across images and countries.
